I think we should add a test like "https://example.com/#\"" to verify what happens when a " appears in the serialized URL.

In Firefox nightly:
JSON.stringify(new URL("https://example.com/#\""))  
 "https://example.com/#%22"

With my patch:
JSON.stringify(new URL("https://example.com/#\""))
 "\"https://example.com/#\\\"\""

Alex, any thoughts on this? Not super familiar with this so I am not sure what's expected. The URL serialization merely says to append the fragment.

Either way, this would be an issue with our serialization and would also impact the stringier, not only the new toJSON.

Chris, the difference you are seeing is because Firefox encodes more code points during parsing of the URL fragment. Firefox is the only browser to do so, so I think the results of your patch are indeed what you should be seeing here. See https://url.spec.whatwg.org/#fragment-state in particular.
